I joined Reddit in 2006, so I remember a time before subreddits. I remember when upvotes and downvotes actually meant "contributes to the discussion" or "does not contribute to the discussion". Reddit has degenerated into hive-mind group think, which is often wrong, and is completely unaccepting of views counter to the group. I always thought Slashdot's approach to voting to be superior - categories of votes rather than a single blunt instrument.
I actually hope Reddit fails now. It hasn't been an enjoyable place for discussion in years.
